LoUIs B. STINE, or NILES CENTER, ILLINOIS, AssIGNoR: 'IO CRANEGOW Y ILLINOIS, A coItroRA'rIon or ILLINOIS 1 I CLOSET BOWL WITH SPRAY RECEPTOR Application filed Mach 22 1930. serial No. 438,034.

This invention relates to plumbing fixtures and particularly to means for preventing back siphonage of water from the plumbing fixture into a fresh water supply line.

In certain instances and particularly in hospital fixtures it is desirable to have an attachment thereto which may be used for flushing and washing separate receptacles such as bed pans or the like. For such pur poses it is customary to supply a closet bowl or some fixture with a separate spray attachment whereby the receptacleto be cleansed may be held over the fixture and washed by means of a spray nozzle. It has been customary heretofore to provide a spray nozzle integral with the fixture or also to provide a spray nozzle which is separable from the fixture but which may be placed in the receptacle when not in use.

In many instances in the past where a spray hose and nozzle was used and care was not taken to place the nozzle above the water line in the bowl, or if thebowl became subsequently clogged, raising the water level therein, the hose nozzle became submerged in the soiled water of the bowl. This permitted drawing the soiled water into the supply line by suction action occurring past a leaky seat in the nozzle valve.

It is the purpose of this invention to provide a closet bowl or the like, which has a receptor for a spray nozzle as an integral part of the bowl and which is so located that the foregoing condition becomes an impossibility.

It is within the contemplation of this invention to place this receptor above any posof'a closet bowl constructed 'in accordance withthis invention. 1

Referring more particularly, to 'the. figures, there is shown-for purposes of illustration a closet bowl 1 having a rim portioniQl formed sides of the bowlpfior cleansing the bowl. A water supply or connection 4 having the usual flush valve and shut-off valve therein enters the side of the bowl to supply the flush-- ing water. The closet bowl is formed at its rear end with an upstanding oval neck 5 open at its top and defining a closed receptacle chamber'G, the bottom of which is closed; by a wall 7 having one or more small apertures 8 therein leading into the bowl portion of the fixture. The wall 7 ispositioned above the level of rim 2 in order that it may be above any possible water level within the. closet bowl.

The customary spray hose 11 is shown and terminates in a spray nozzle 12, the latter .in the shape of ;a conduit and apertured as at 8 todistribute freshwater around the being controlled by hand valves 16. The hose may be supplied from fresh water line 14: through valve 16. V

In operation the spray hose may be used to cleanse a receptacle such as .a bed pan and upon completion may be inserted in chamber 6 with the spray nozzle resting over-: aperture 8 which is small enough to prevent the spray from passing therethrough. The spray may therefore drip into a closet bowl and yet will be held out of contact with the water in the bowl regardless of the level ofthe water in the bowl, even though the bowl be filled to the point of overflowing the highest' possible water level being indicated in Figure 2.

In the foregoing description a closet bowl? with the integral receptor has been shown for purposes of illustration only, it being apparent that any other form of fixture may be provided with a receptor formed inte scope of this invention. It is also obvious that changes may be made in the details of construction of the illustrated form and other forms without departing fromthe spirit and;

I claim:

In combination, a plumbing fixture having a bowl terminating in arim, a fresh water supply line connected to said bowl, the connections thereto includinga flush valve for controlling the supply of water to said bowl, I an auxiliary hose connection frome said fresh 10 Water supply,said hose connection beingof suflicient length to extend into said bowl a portion of the upper edgeof the bowl being 7 extended above the remainder thereof and shaped to provide a receptor adapted to 'r'eceive theend of said hose,' said receptor hav: ing an apertured bottom positioned above the rim of said bowl and above any possible overfiowlevel of the bowl, the aperture communieating with said bowl to drain the receptacle CERTIFICATE OF GORREGTIGN.

Patent No. 1,878, 910. September 20, 1932.

LOUIS B. STINE.

It is hereby certified that error appears in the printed specification of the above numbered patent requiring correction as follows: Page 1, after line 29, insert the following paragraph:-

This suction action may be caused for example, if there is a failure in the Water supply or the supply itself is shut off and a person attempts to draw water from the supply system at a point below the clogged bowl. The Water from the bowl may thus easily be siphoned back into the fresh water supply line. Obviously, such contamination, with the probability of contagion, is a condition to be much avoided.

and thatthe said Letters Patent should he read with this correction therein that the same may conform to the record of the case in the Patent Office.
